Bug#1087600: python3.13: Please include temporary patch to fix FTBFS on m68k

[John Paul Adrian Glaubitz]

Source: python3.13
Version: 3.13.0-2
Severity: normal
Tags: patch
User: debian-68k@lists.debian.org

Hello,

the package python3.13 fails to build from source on m68k due to alignment
issues.

This is fixed with the following patch:

Index: python3.13-3.13.0/Include/internal/pycore_gc.h
===================================================================
--- python3.13-3.13.0.orig/Include/internal/pycore_gc.h
+++ python3.13-3.13.0/Include/internal/pycore_gc.h
@@ -19,7 +19,7 @@ typedef struct {
     // Pointer to previous object in the list.
     // Lowest two bits are used for flags documented later.
     uintptr_t _gc_prev;
-} PyGC_Head;
+} PyGC_Head Py_ALIGNED(sizeof(uintptr_t));
 
 #define _PyGC_Head_UNUSED PyGC_Head
 
I'm attaching it as a separate diff.

I hope that we will be able to waive for this patch in the future when we
switch the m68k port to 4-byte alignment.

Thanks,
Adrian
